To all whom it may concern:

Be it known that I, MICHAEL Cnon'n, a citizen of the United States, anda resident of Indianapolis, county of Marion, and State.

of Indiana, have invented a certain useful Sofa-Bed; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings.

The object of this invention is to improve the construction of sofa beds.

" angle bar shown in Fig. 2.

The features of the improvement will appear from the accompanying drawings and the followingdescription and claims.

In the drawings Figural is a central vertical transverse section through a sofa bed when it is folded up. Fig. 2 is a bottom view of an outer corner of the wire mattress frame unfolded on the line 2-2'of Fig. 5. Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. =1 is a side elevation ofa ortion of the Fig. 5 is a central vertical section through. the sofa bed when it is unfolded. Fig. 6 is a sectionon the line 6--6 of Fig. 5, through a part of the device. Fig. 7 is a plan view-of one end of the device when it is unfolded, showing the wire mattress, parts being broken'away.

Fig. 8 is a vertical section on -the line 88 of Fig. 7. Fig. 9 is a perspective view 0 a portion of the mattress frame and its associated parts, parts being broken away.

Fig. 10 isa section on the line 10-10 of Fig. 9.

feature of the invention consists in be termed herein, a seat frame practically independent, or at least, quite readily detachable, from the sofa frame. The sofa frame consists ofthe' ends 10, back 11 and the bottom frame 12. This latter is a rectangular frame consisting of front, rear. and end bars and is secured at its ends to the ends 10. The seat frame consists of a stationary member 13 and a'folded seat member 14 hinged together by the hinges 15 at one side. They are rectangular frames, the lower member 13 consisting of a front and two end pieces andsaid frame rests above the bottom 12 of the sofa frameand is held in place thereon by the machme screws 18 which extend through-the ends '10 and screw into endsof the lower member 13 of the seat frame. By loosening the bolts 17 the seat frame can be lifted out of the sofa frame.

One

having, what may secured to the three sections the nuts 18 embedded in the Hence, the device is easy to ship as the ends and back can be shipped knockeddown and likewise the seat frame can be separately shipped and anybody, without slcill, can readily assemble the two frames. The upper member 1 1 of the scat frame has front and reartop bars 19, when folded up as shown, in Fig. 1, on which an upholstered seat 20 is located. 14 is unfolded the upholstered portion 20 is on the underside, as shown in Fig. 5, and

the outer end of the unfolded seat portion is supported by pivoted legs 21 of familiar YP- i 1 The mattress frame consists of three sections, an inner section'22 which is also over the member13 of the seatframe, an outer section 23 which when the device is unfold ed, is over the seat member 14 of the seat frame, andan intermediate section 24 which is pivoted at its ends to the other two sections 22 and 23. These sections 22, 23 and 24 are made of angle iron or any other suitable material, the sections 22 and 23 having three sides. The intermediate section 24: consists of bars at each side of themattress frame centrally pivoted on a stand 123 which is secured to the inner bar 19 of the seat member said seat member is folded up, as shown in Fig. 5. hen the device is folded up the stand 123 extendsdownwardly from the seat frame, as shown in Fig. 1.

- A. single wire mattress 30, see Fig. 7, is of the mattress frame and closes in between them when said sections are folded to the position shown in Fig. 1. The sections 22 and 2 3 of the mattress frarne have angle'brace bars 31, see

Fig. 7, secured at their corners. In the folded position, the section 23 of the mattress frame lies above the section 22 and they mediate section 24 which the parts are folded up. To"permit the properplay of the intermediate section is vertical when or movement 24 the bars 123 are mounted and also through a connect- \Vhen said seat member 14 of the seat frame, when are spaced and held apart by the interthereof are provided with longitudinal slots ms 123 and intermediate bar 24,

log bar This connecting bar extends rearwardly and at its rear end is curved downwardly and is pivoted at 37 to the free ends of the link bars 38 and '39 which are pivoted at their ends respectively to the ends of the member 13 of the seat frame, and the ends of the section 22 of the mattress frame, see Fig. The posts 123 support the mattress frame appreciably above the seat frame when the couch is unfolded, see Fig. 5, and the connecting barshold the links 38 and 39 almostin vertical alinement with each;

other and thereby the rear portions of the mattress section 23 are supported at the same elevation and maintained in horizontal position when the mattress frame is un folded.

, 1V hen this is The outer portion of the outer section 23' of the mattress frame is supported when the device is unfolded by supporting bars 40 which are pivoted at their lower ends to the ends of the seat frame 14 and at their upper ends are detachably pivoted to the section 23 of the-mattress frame so as to support s aid section 23 in a horizontal position and, in alinement with the other sections of the mattress frame. The bars 40 are pivoted to the secti0n=23 of the mattress frame in the. manner shown in Figs. 2, 3 and t. The bar 4.0 has a. headed pin 4:2 on its upper end adapted to be inserted in the enlarged portion of a slot 4-3 in the end of the mattress frame section 23 and when slid into the reduced portion of said slot the head of the pin 42 prevents escape of the parts. The upper ends of the bars 40 are held normally in the reduced portion of the slot 43 by a. flat spring 45 which is secured by the rivets 4-6 on the inner side of the end of the section 23, see Fig. 2, and dotted lines in Fig. 4. -An L-shaped hand bar 47 is secured to the free end of the spring 45 so that when the hand bar 47 is moved to the dotted line position shown in Fig. 2, the spring will he moved out of engagement with the bar lO so that said bar can be slid laterally to disengage it from the slot in the mattress frame section done the forward parts of the mattress section 23 can be lifted up, after the bed is unfolded, as shown in Fig. 5, and bedding placed in or removed from the seat section 14 of the seat frame. The bed mattress is left on the wire mattress all the time and folds in between the sections thereof. But other parts -of the bedding may be kept between the seat member 14 of the seat frame and the section 22 of the wire II'IH-tlZX'QSS.

A. spring 50 at the rear extends from a portion of the end 10 of the sofa frame to the rear part of the inner section 22 of the mattress frame to assist in supporting the latter, particularly in elevating it from the folded. position shown in Fig. 1, to the unfolded position shown in Fig.5.

Assuming the parts to be folded as shown in Fig. 1, in unfolding it catch the seat near 1ts inner edge and turn it over forwardly to the position shown in Fig. 5. Then the main part-of the connecting bar 35 is sub stantially horizontal and the link bar 38 is inclined outwardly. As the unfolding begins, the lower ends of the posts 123 begin to move both upwardly and slightly to the right of the position shown in Fig. 1. That initial movement pushes the rod 35 endwise to the right which causes the link bar 38 to move upwardly to a substantially horizontal position, its right-hand end moving slightly to the right and upward in a line parallel substantially with the line followed by the pivot 28 as the lower end of the post 123 moves upwardly. After a slight opening movement the pivot- 28 of the post 123 will pass the center line between the hin 'e 15 and theconnection of the bar 35 with the bar 38. It takes a little force'to make the parts pass this center line position in folding or unfolding the same, but after this has been done in the unfolding, the strain of the bars 35 and 38. ceases temporarily and the right-hand ends of said bars drop down practically in the position shown in'Fig. 1.

of the post 123 then begins to pull the bar 35 upward and to the left and the bar 35 draws the outer end'of the link 38 upwardly and this movement continues until the parts assume the position shown in Fig. 5, the two links 38 and 35 being opened like toggles due to the movement of the bar 35 to the left as it goes up and said bar forces the links 38 and 35 to the position shown in Fig. 5, and thereby they are enabled to support the mattress frame 22. In folding up the device the parts will operate reversely to what hasbeen described. Therefore, it is observed that in this device, the sofa frame, seat frame and mattress frame are all in a sense independent, or at least separable frames, which may be readily put together or separated for shipping or other purposes and each of these frames possesses, to a certain extent, its own peculiar individuality in construction and operation.

In the second place there is novel means for controlling the movement of the sections of the mattress frame and maintaining the inner section in its elevated position;

In the third place, the means for supporting the outer section of the mattress frame are detachable therefrom so that it can be turned up for the insertion and. removal of bedding in the space between the mattress frame and seat. a

The invention is not intended to be limited to a direct pivoting of the intermediate mattress frame section to the seat posts, so long as the connection is such as to permit 1 said sections to turn on said posts.
